27 CASITAS MUNICIPAL WATER DISTRICT MEMORANDUM

TO: BOARD OF DIRECTORS FROM: MICHAEL L. FLOOD, GENERAL MANAGER SUBJECT: OJAI EAST RESERVOIR RESIDUAL MANAGEMENT SYSTEM, SPECIFICATION NO. 20-435 DATE: 11/12/2020

RECOMMENDATION:

Award a contract to UGSI Solutions Inc. (UGSI) for the Ojai East Reservoir Residual Management System equipment, Specification No. 20-435 in an amount not to exceed $71,900 and authorize the General Manager to sign a contract for installation of the equipment and construction of the facilities within the Fiscal Year 20-21 budget of $150,000.

BACKGROUND:

The Casitas water system includes 14 tanks totaling 30 million gallons of storage and approximately 160 miles of pipelines. A substantial amount of time is needed to reach the easternmost portions of the system, which causes excessive water age and degrading water quality. The three-million gallon Ojai East Reservoir on the east end of the Casitas system receives water from Lake Casitas and the Mira Monte Well. Water quality degrades as water moves to the easternmost portions of the system, such that water quality improvements are needed at Ojai East Reservoir, before water supplies continue toward the 4(M) Reservoirs, Upper Ojai Reservoir, and 3(M) Reservoir. The proposed Residual Management System installed at the Ojai East Reservoir site will regulate disinfection residual while reducing both nitrification potential and disinfection byproduct formation, as well as reduce staff time required to perform manual residual management of the easternmost reservoirs. Staff pursued pricing from three vendors, each of which has a proprietary approach to meeting water quality criteria. Three vendors provided quotes as shown in Table 1.

Table 1 – Ojai East Reservoir Residual Management System Equipment Quotes UGSI $71,900 D&H $69,900 Medora $109,207

District staff evaluated the proposed system components, checked references, and considered operational and maintenance of the systems. Medora could not provide references for an installed system to evaluate their performance so they were not considered further. UGSI’s system was

28 Ojai East Reservoir Residual Management System, Specification No. 20-435, Equipment Procurement November 12, 2020 Page 2 deemed the most compatible with the District’s needs, even though it is slightly more expensive than the D&H system. The UGSI system includes: • Smart Control Center • Chlorine and ammonia feed system • Hypochlorite storage tank • Liquid ammonium sulfate storage tank • Sample recovery pump • Water quality system • PWM500 mixer wet assembly and tripod • Control center dry assembly with SCADA compatibility

District staff will assemble a separate package for bidding the installation of the equipment.

FISCAL IMPACT:

The FY 2020-21 Budget includes funding of $150,000 for this project.

Michael Shields Casitas Water District

Re: Monoclor® Residual Control System for Casitas MWD, CA PSI Water Technologies, Inc. File No.: P16-2586 (Firm)

Dear Michael,

Thank you for your interest in PSI Water Technologies, Inc. (PSI), a UGSI Solutions company. We have prepared this firm proposal for providing a Monoclor® Residual Control System (RCS) for 3MG East Ojai Tank. Our proposal is based on the following design criteria:

Design Criteria

Reservoir Diameter, ft 115 Reservoir Height, ft 36 Maximum Capacity, MG 3 Maximum Flow, MGD 1 Reservoir Type Circular, Above-Ground Disinfectant Chloramines Desired Chlorine Residual, ppm 3.0 Chlorine Demand, ppm 0.5 Chlorine Dose, ppm 3.5 Peak Chlorine Demand, ppd 30

System Features & Advantages

The Monoclor® RCS is an intelligent, automated disinfectant boosting system that gives operators the ability to set and control residual levels in water storage tanks and key locations in the distribution system. The Monoclor® RCS utilizes advanced water quality sensors, powerful active mixing, an automated chemical feed system, and an advanced control algorithm to set and maintain residual levels in water storage tanks and distribution systems. The Monoclor® RCS has been tested and validated through extensive laboratory testing and many full-scale installations over the last 5 years.

Our Monoclor® RCS consists of all equipment essential for a complete system, including:

1. Accurate chemical dosing at the correct ratio 2. Proper mixing to ensure a homogenous water body that will not stratify 3. High energy mixing that ensures instantaneous reaction of introduced chemicals 4. Real-time monitoring and control logic to maintain or achieve equilibrium by responding to dynamic reservoir conditions

T: (310) 975-9719 M: [email protected] W: 4psi.net

The Monoclor® RCS enables operators to:

1. Set and maintain consistent disinfectant levels in storage tanks and key locations in the distribution system 2. Continuously blend disinfectant residual and eliminate thermal and chemical stratification 3. Eliminate costly and labor-intensive manual boosting 4. Quickly counteract adverse water quality changes, such as low residual 5. Optimize and balance disinfectant levels across a water distribution system

The PAX PWM500 mixer is a submersible active mixing system for potable water storage tanks and reservoirs. When operated correctly, the PAX PWM500 mixer can rapidly eliminate thermal stratification, decrease ice formation, rapidly blend and distribute doses of residual disinfectant, and maintain uniform chemical and temperature conditions. Under some conditions, the mixing action can also reduce the rate of residual disinfectant loss and lower volatile disinfection byproduct levels inside the tank when used as part of an in-tank aeration system.

The Tank Shark® Mixing System provides essential mixing energy to maintain a completely homogeneous reservoir using only the motive water passing through the mixing nozzle assembly. The upward force of the flowing water stream mixes colder water from the base of the reservoir with the warmer layers near the top while simultaneously blending any volume of water stratified by residual level. This removes any concerns resulting from aged water or structural damage due to ice. A sample pump continuously draws fluid through a sample line attached to the Tank Shark® system through the water sampling cabinet for analysis directly from the up-swelling stream of reservoir water.

Our scope of supply follows in Section 1 and our mixer performance guarantee in Section 2. Section 3 includes our proposal acceptance while Section 4, 5 and 6 includes terms and conditions, technical information and case studies. Lastly, Section 8 will includes product brochures.

We look forward to working with you on this project. If we can be of any further assistance, please do not hesitate to contact me at (310) 975 - 9719.

Sincerely,

Kevin Sanner Regional Sales Manager

39 CASITAS MUNICIPAL WATER DISTRICT MEMORANDUM

TO: BOARD OF DIRECTORS FROM: MICHAEL FLOOD, GENERAL MANAGER SUBJECT: AMENDMENT TO PROFESSIONAL SERVICES AGREEMENT FOR VENTURA-SANTA BARBARA COUNTIES INTERTIE ENVIRONMENTAL CONSULTING SERVICES DATE: 11/12/20

RECOMMENDATION:

Approve and authorize the General Manager to amend the agreement for professional environmental consulting services with Rincon Consultants for the Ventura-Santa Barbara Counties Intertie for a fee not to exceed $51,574.

BACKGROUND AND DISCUSSION:

The Ventura-Santa Barbara Counties Intertie project includes approximately 8,200 feet of 16- inch pipeline and a two booster pump stations to connect the Carpinteria Valley Water District (CVWD) and Casitas systems. The Board approved an agreement with Rincon Consultants, Inc. (Rincon) in March 2019 to provide environmental consulting services, including the preparation of an Initial Study-Mitigated Negative Declaration in compliance with the California Environmental Quality Act (CEQA). An amendment was approved in July 2019 to include revisions to the pipeline alignment, additional pump station, and additional meetings and coordination.

The Administrative Draft Initial Study-Mitigated Negative Declaration was submitted to the District in January 2020 and placed on hold for funding reasons. Recently, the District submitted an application to the State Water Resources Control Board (SWRCB) for a Drinking Water State Revolving Fund (SRF) loan through the Additional Supplemental Appropriations for Disaster Relief Act (ASADRA) program for the project. This program requires environmental documents to be in compliance with CEQA and Federal ‘cross-cutting’ requirements. Additionally, since more than a year has passed since environmental studies were performed, some must be updated. The timeframe for project completion, if the loan is approved by SWRCB and the District, is three years. District staff would like to complete the environmental compliance to stay on track and not hinder project completion.

Rincon has submitted a request to provide services to update the CEQA document and provide the necessary Federal compliance. Permitting assistance is also included. Table 1 summarizes the requested scope of services.

This amendment increases the total budget for Rincon’s services from $133,566 to $185,140. The revised Administrative Draft IS-MND is expected to be provided to Casitas in four weeks.

BUDGET IMPACT:

This project is not included in the fiscal year 2020-21 budget. An appropriation of $60,000 is requested to cover the amendment and a contingency.

Subject: Revised Amendment No. 2 to Provide Environmental Consulting Services for the Ventura-Santa Barbara Intertie Project, Ventura and Santa Barbara County

Dear Ms. Aranda: The purpose of this letter is to request a revised scope and budget amendment to the existing agreement for the Ventura-Santa Barbara Intertie Project (project) between Casitas Municipal Water District (Casitas) and Rincon Consultants, Inc. (Rincon). This revised Amendment No. 2 is intended to address additional effort needed to complete the environmental review for the project, which is anticipated to exceed the effort anticipated in our original contract dated March 27, 2019 and the contract Amendment No. 1 dated July 10, 2019 for this assignment. Additional tasks are necessary due to the temporary suspension of the environmental consulting efforts since January 7, 2020 as directed by Casitas, as well as the addition of a new funding pursuit. Understanding of the Project

Rincon understands the fundamental design characteristics of the project have not changed since the project was put on hold on January 7, 2020. The proposed project involves the construction and operation of potable water infrastructure to connect the Casitas and Carpinteria Valley Water District (CVWD) water transmission systems. The proposed project has been refined to include approximately 1.4 miles of 16-inch-diameter potable water pipeline, two booster pump stations, and improvements to infrastructure at existing Casitas facilities. The pipeline would traverse the boundary between Ventura and Santa Barbara counties and act as a two-way intertie to allow the transfer of water between Casitas and CVWD, as necessary. It is our understanding Casitas is still pursuing project funding through the Federal Emergency Management Agency’s (FEMA) Hazard Mitigation Grant Program, which is administrated with the assistance of the California Office of Emergency Services (Cal OES). This scope of work and cost estimate include tasks to assist Casitas with meeting the requirements for federal funding through the Hazard Mitigation Grant Program. It is also our understanding Casitas is now pursuing project funding through the California State Water Resources Control Board (SWRCB) State Revolving Fund (SRF) Program. Consequently, the California Environmental Quality Act (CEQA) documentation needs to meet CEQA-Plus standards, which require more extensive documentation related to federal regulations than is required for a typical CEQA analysis. In addition, based on our experience with the SWRCB SRF Program, it is our understanding they

Environmental Scientists Planners Engineers 42 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

prefer CEQA-Plus documents analyze only the preferred project alternative, rather than a range of alternatives. They require a separate alternatives analysis also be submitted with the funding application. Therefore, we recommend the CEQA-Plus document be updated to analyze only the preferred project alternative. Remaining Scope of Work

The remaining scope of work includes the following tasks.

Task 1. Project Initiation The project initiation task has been completed.

Task 2. Biological Resources Assessment The Biological Resources Assessment was completed in July 2019. The SRF Program requires United States Fish and Wildlife Service (USFWS) species lists in biological reports be less than one year old. The species list in the Biological Resources Assessment is dated May 2019. Therefore, Rincon will acquire an updated species list for the project area and update the Biological Resources Assessment accordingly. Based on our experience with the SRF Program, it is our understanding the supporting documentation can evaluate a range of alternatives if the IS-MND itself evaluates the preferred engineering alternative. Rincon assumes no further revisions will be needed to the Biological Resources Assessment.

Task 3. Cultural Resources Technical Study For the purpose of National Historic Preservation Act (NHPA) Section 106 approval, which is required for the FEMA Mitigation Hazard Grant Program and SRF Program, cultural resources record searches and field surveys must have occurred within the last two years. The cultural resources record searches for the project occurred between May 10 and June 12, 2019, and the field surveys occurred between May 21 and June 14, 2019. Therefore, if NHPA Section 106 approval is obtained before May 10, 2021, no change or additional work to the Cultural Resources Technical Study is required. Based on our experience with the SRF Program, it is our understanding the supporting documentation can evaluate a range of alternatives if the IS-MND itself evaluates the preferred engineering alternative. No change or additional work is assumed to be required for the Cultural Resources Assessment.

Task 4. Paleontological Resources Assessment Based on our experience with the SRF Program, it is our understanding the supporting documentation can evaluate a range of alternatives if the IS-MND itself evaluates the preferred engineering alternative. The paleontological resources assessment has been completed, and it is assumed no change or additional work is required.

Task 5. Administrative Draft IS-MND In January 2020, the public review version of the Draft IS-MND was completed but not yet circulated. Because the IS-MND must now meet SRF Program requirements, Rincon will revise the Administrative Draft Initial Study-Mitigated Negative Declaration (IS-MND) to support Casitas’ SRF Program funding

Page 2 43 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

pursuit. This includes updating the “Federal Cross-Cutters” chapter as needed. In addition, Rincon will revise the Draft IS-MND to evaluate only the preferred engineering alternative, which we understand to be Segment 1, Segment 2B, Segment 3B; BPS-A1; BPS-B2; and the additional improvements of existing infrastructure. Rincon will refine environmental impact analyses and mitigation measures to apply only to the preferred engineering alternative. As discussed under Task 9, Federal Clean Air Act Conformity analysis, the United States Environmental Protection Agency (U.S. EPA) approved EMFAC2017, the latest vehicular air pollution emissions factors for use by state and local governments to meet Federal Clean Air Act (FCAA) requirements, for use in August 2019. The U.S. EPA established a one-year grace period for using the previous emissions factors (EMFAC2014), which expired in August 2020. CalEEMod relies on EMFAC2014 and therefore can no longer be used for FCAA conformity analyses. Due to the SRF Program funding submittal, the FCAA Conformity Analysis needs to be updated. Rincon will update the air quality and greenhouse gas (GHG) modeling in the FCAA Conformity Analysis and Draft IS-MND to instead use the Roadway Construction Emissions Model (RCEM), which relies on the updated EMFAC2017 emissions factors. CalEEMod is generally more conservative than RCEM, so we assume the RCEM calculated emissions will be reduced as compared to the previous analysis. Rincon will notify Casitas immediately if the modeled emissions increase and require mitigation to reduce potential impacts to a less-than-significant level. Rincon assumes previously conducted noise modeling will not need to be updated. Because of the time lapse since completion of the previous public review Draft IS-MND, Rincon will review the Draft IS-MND to ensure no other changes to the document are necessary prior to publication. Rincon will also refine the Alternatives Analysis based on the information in the Administrative Draft IS- MND. Rincon will provide the Administrative Draft IS-MND in electronic format for Casitas review. Rincon will revise the Administrative Draft IS-MND based on one round of consolidated comments from Casitas to be provided in an electronic, editable format.

Task 6. Public Review Draft IS-MND Rincon will prepare the Administrative Public Review Draft IS-MND upon confirmation from Casitas all previous comments have been adequately addressed. An electronic pdf version will be submitted to Casitas for final approval. Rincon will provide a PDF electronic version for posting on Casitas’ website and submit the document to the State Clearinghouse on behalf of Casitas. Rincon will also distribute a Notice of Intent (NOI) to Adopt an MND to up to 20 mailing addresses and file the NOI with the Ventura and Santa Barbara County Clerks. We assume Casitas will be responsible for publishing the notice in a local newspaper(s) and/or noticing via direct mailing to the owners and occupants of property contiguous to the project site, as well as payment of required County Clerk filing fees; however, if desired, Rincon can coordinate such noticing at an additional cost. Additionally, hardcopies of the Draft IS-MND can be provided at an additional cost upon request.

Task 7. Final IS-MND Upon receipt of public comments on the Draft IS-MND, Rincon will prepare draft responses to comments and the administrative Final IS-MND for Casitas review. We assume minimal public comments on the Draft IS-MND will be received due to the rural setting of the project area and the project type (potable water pipeline for emergency purposes). However, if there is a substantial number

Page 3 44 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

of comments requiring a response, a budget amendment may be required. Rincon will also prepare the Mitigation Monitoring and Reporting Program (MMRP). The MMRP will list in tabular format the mitigation measures and corresponding monitoring requirements, the entities responsible for monitoring and completing the mitigation, and schedule for mitigation implementation. Rincon will provide the administrative Final IS-MND (including draft responses to public comments and the MMRP) in electronic format for Casitas review. Rincon will revise the Final IS-MND based on one round of consolidated comments from Casitas to be provided in an electronic, editable format. Rincon will then provide electronic versions of the Final IS-MND to Casitas for distribution. Upon adoption of the Final MND and approval of the project, Rincon will prepare and file with the State Clearinghouse and County Clerks the Notice of Determination (NOD). We assume Casitas will be responsible for paying applicable filing fees. We can coordinate payment of the required fees, if desired, pursuant to written authorization to invoice the fee amounts. Hardcopies of the Final IS-MND can be provided at an additional cost upon request.

Optional Task 8. Regulatory Permitting The crossing of Rincon Creek by the proposed pipeline will likely trigger the need for Casitas to obtain one or more regulatory permits. Rincon will complete a jurisdictional delineation at the creek crossing area (Subtask 8.1), and, based on the method used to cross the creek, will prepare applications/notifications for compliance with the Clean Water Act (Sections 404 and/or 401) and/or California Fish and Game Code (Section 1602), as necessary. Similarly, Rincon will prepare a Biological Assessment (BA) for use during federal Endangered Species Act Section 7 consultation for potential impacts to California red-legged frog, steelhead, tidewater goby, southwestern willow flycatcher, and least Bell’s vireo (Subtask 8.2). We assume electronic submissions will be accepted for all regulatory permitting applications/notifications. Hardcopies can be provided at an additional cost upon request.

Subtask 8.1. Jurisdictional Delineation Report Rincon will conduct a jurisdictional delineation of waters of the United States and state of California, including wetlands, on the project site using the most current guidance provided by the regulatory agencies. Wetlands within the project site will be classified, documented, and mapped in general accordance with Corps of Engineers Wetlands Delineation Manual and Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region. The Ordinary High Water Mark will be delineated in general accordance with the methods prescribed in A Field Guide to the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States and Updated Datasheet for the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States. Rincon will delineate the boundaries of jurisdictional features with special emphasis on features subject to jurisdiction by the United States Army Corps of Engineers (USACE), State Water Resources Control Board (SWRCB), and California Department Fish and Wildlife (CDFW). The results of the delineation will be presented in a standalone report suitable for submittal as an attachment to the permit applications (see Subtasks 8.3 through 8.5). Rincon will submit electronic versions of the report for Casitas review. The report will be revised based on one round of consolidated comments from Casitas to be provided in an electronic, editable format.

Page 4 45 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

Subtask 8.2. Biological Assessment Rincon will prepare a BA in accordance with the requirements of Section 7(a)(2) of the federal Endangered Species Act (16 United States Code 1536(c)) and interagency implementing regulations at 50 Code of Federal Regulations 402. The BA will serve to facilitate Section 7 consultation between the USACE and USFWS as part of the Section 404 Permit (Subtask 8.3). The BA will describe the methods and results of the previously conducted literature and database review, vegetation mapping, and field assessment, including a figure depicting vegetation communities, habitat types and any observations of federally listed species on the project site (which was completed as part of the Biological Resources Assessment). The BA will identify the potential for federally listed species and/or critical habitat to occur. The BA will also address effects to federally listed species, include conservation measures to reduce the likelihood and magnitude of identified effects, as well as include an effects determination for each federally listed species.

Subtask 8.3. Section 404 Permit Application If the project will impact USACE jurisdictional areas, Rincon will prepare an application for the USACE. Based on our understanding of the project, we believe a Nationwide Permit (NWP) 12, Utility Line Activities, will be the most applicable permit for the project to achieve compliance with federal Clean Water Act (CWA) Section 404. Nationwide Permit 12 authorizes “activities required for the construction, maintenance, repair, and removal of utility lines and associated facilities in waters of the U.S., provided the activity does not result in the loss of greater than 0.5-acre of waters of the U.S. for each single and complete project”. The Jurisdictional Delineation Report (completed under Subtask 8.1) and accompanying application will be prepared and provided to Casitas to review. Upon approval, we will submit the application on behalf of Casitas to the USACE Los Angeles District. Generally, under a Nationwide Permit, application review by the USACE takes 4 to 6 months. For the purpose of this proposal, we have assumed the project will qualify for an NWP and an Individual Permit (IP) will not be necessary. Should an IP be determined necessary, we can support this permit process under a separate scope and cost. As part of the CWA Section 404 permit process, the USACE is required to consult with USFWS regarding potential impacts to federally listed wildlife species. This process is referred to as an Endangered Species Act Section 7 Consultation. The California red-legged frog has a low potential to occur within the Study Area, and is not expected to be impacted by the project. Under Section 7, federal agencies (i.e., USACE) must consult with the USFWS when any action the agency carries out, funds, or authorizes (such as through a permit; 404 permit) may affect a listed endangered or threatened species. This process usually begins as informal consultation. Consultations are initiated when the USACE issues a letter to the USFWS to request the initiation of Section 7 consultation. The USACE will generally submit the BA with the letter to request the initiation of Section 7 consultation. If, during the informal consultation process (approximately 30 days from receipt of the letter request), the federal agency (USFWS) determines the proposed project may affect, or is likely to adversely affect, a listed species and/or critical habitat, the USACE will submit to the USFWS a request for formal consultation. In accordance with regulations in 50 Code of Federal Regulations 402.14 (Formal Consultation), formal consultation may last up to 90 days, unless the agencies request an extension to no more than 150 days, after which the federal agencies are allotted 45 additional days to prepare a Biological Opinion. We anticipate informal consultation with the USFWS may be required; formal consultation with the USFWS is not anticipated.

Page 5 46 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

Subtask 8.4. Section 401 Water Quality Certification Application Rincon will prepare a Notice of Intent (NOI) for a CWA Section 401, Water Quality Pre-certification from the Regional Water Quality Control Board (RWQCB), verifying that the project activities will comply with State water quality standards. Rincon will submit the NOI to Casitas for review. Upon approval, Rincon will submit the application on behalf of Casitas to the RWQCB. Review and approval of the Section 401 certification typically requires four to six months for completion. Rincon will follow up with the RWQCB to facilitate a timely review of the permit application and request expedited review as possible. In addition, the RWQCB has new procedures applicable to the Section 401 process became effective on May 28, 2020, which are likely to increase the time and cost for acquiring water quality certifications. These procedures are not anticipated to apply to RWQCB General Orders for existing pre-certified NWPs such as NWP 12. Should this assumption change, we would revisit the scope and cost for this task. It is assumed Casitas will be responsible for the application processing fee.

Subtask 8.5. Section 1602 Streambed Alteration Agreement Application If the project would impact CDFW jurisdictional areas, Rincon will prepare an application for issuance of a Streambed Alteration Agreement (SAA) pursuant to Section 1602 of the California Fish and Game Code. Rincon will input all information required to apply for the Standard SAA through the CDFW moderated Environmental Permit Information Management System (EPIMS). Prior to submittal of the notification via the online portal system (EPIMS), Rincon will schedule a meeting with Casitas to provide guidance on how to review the application materials via the portal system. Once Casitas has reviewed the application, Rincon will submit the application to CDFW via the EPIMS portal. It is assumed Casitas will be responsible for payment of the notification fee.

Task 9. Federal Clean Air Act Conformity Analysis The U.S. EPA approved EMFAC2017, the latest vehicular air pollution emissions factors for use by state and local governments to meet FCAA requirements, for use in August 2019. The U.S. EPA established a one-year grace period for using the previous emissions factors (EMFAC2014), which expired in August 2020. CalEEMod relies on EMFAC2014 and therefore can no longer be used for FCAA conformity analyses. Due to the SRF Program funding submittal, the FCAA Conformity Analysis needs to be updated. Rincon will update the air quality and GHG modeling in the FCAA Conformity Analysis and Draft IS-MND to instead use the Roadway Construction Emissions Model (RCEM), which relies on the updated EMFAC2017 emissions factors. CalEEMod is generally more conservative than RCEM, so we assume the RCEM calculated emissions will be reduced as compared to the previous analysis. Rincon will notify Casitas immediately if the modeled emissions increase and require mitigation to reduce potential impacts to a less-than-significant level.

Task 10. Public Meeting/Hearing Rincon’s Project Manager and/or Principal-in-Charge will attend one virtual public meeting or hearing related to the IS-MND. Attendance will include an oral presentation, if requested by Casitas. If needed, Rincon will attend additional meetings or hearings on a time-and-materials basis, in accordance with our standard fee schedule.

Page 6 47 Casitas Municipal Water District Ventura-Santa Barbara Intertie Project

Task 11. Project Management Project management tasks include in-house management of Rincon staff during the remainder of this scope of work, responding to telephone calls and emails regarding the project, monitoring the project budget and schedule, and other similar tasks.

Optional Task 12. AB 52 Consultation Assistance Assistance with Assembly Bill 52 consultation has been completed, and no change or additional work is required. Schedule

Rincon will work with Casitas to provide submittals in a timely manner. Upon receipt of authorization to proceed, we will coordinate with Casitas to prepare a schedule for completion of the California Environmental Quality Act and regulatory permitting processes. The revised Administrative Draft IS- MND can generally be submitted for review within four weeks of authorization to proceed. Cost Estimate Our cost estimate for the remaining scope of work is $29,627, excluding Optional Task 8 (Regulatory Permitting). With Optional Task 8 included the overall cost is $58,871. The table on the following page shows a breakdown of costs by task. Based on the original contract and Amendment No. 1 dated March 27 and July 10, 2019, respectively, the total fee for services was $133,566. To date, we have spent $126,383 with a remaining contract amount of $7,297 Therefore, to complete the remaining work stated above in this letter, Rincon is requesting an additional $51,574, with Optional Task 8 (Regulatory Permitting). Closing This proposal is valid for a period of 30 days and is fully negotiable to meet the needs of Casitas. We appreciate the opportunity to continue to assist Casitas with this project. Please let us know if you have any questions regarding this proposal. Sincerely, Rincon Consultants, Inc.

Casitas Municipal Water District ii Hydrology Report Water Years 2018 and 2019

1. INTRODUCTION Casitas Municipal Water District (CMWD or Casitas), in cooperation with the Ventura County Watershed Protection District (VCWPD) and the U.S. Geological Service (USGS), collects hydrology data on the Ventura River system. Figure 1-1 shows the watershed boundaries including drainage areas, stream gaging stations, and weather stations. The hydrology data is a valuable asset for developing an understanding of the water resources of the Ventura River system. Since 1981, CMWD has summarized the data into a series of annual reports. This report presents information and data for the 2017–2018 Water Year (WY 2018) and 2018–2019 Water Year (WY 2019). Data is also presented for Calendar Years 2018 and 2019 for comparison to historical data.

Casitas acquired the Ojai Water System in June 2017 which serves approximately 3,000 customers. The main water source for this system is a wellfield which draws from the Ojai Valley Groundwater Basin, located within the San Antonio Creek Watershed, a sub-basin to the Ventura River Watershed. The Ojai Water System is supplemented by surface water deliveries from Casitas Reservoir (also referred to as Lake Casitas herein), particularly in times of drought and/or high demand when aquifers are typically depleted and well production is reduced or limited.

Ventura County experienced a major fire (the Thomas Fire) in WY 2018 which burned nearly the entire watershed, as shown in Figure 1-2. Hydrologic impacts following the Thomas Fire were observed in both the direct and indirect inflow sources of Lake Casitas. This included steeper hydrographs at increased magnitudes during storm events from a combination of hydrophobic soil limiting percolation rates and less vegetation to slow surface run-off. Heavy debris and sediment loads from slope erosion and streambed mobilization during high magnitude storm events impacted diversion capabilities at the Robles Diversion and Fish Passage Facility (Robles). Heavy debris loads clogged the diversion screens requiring frequent turnouts to manually clean the screens and replace brush motor sheave belts. Diversion capabilities were also reduced due to sediment in the Robles Screenbay and Forebay. Two shutdowns occurred in order to remove sediment from the Screenbay in the winter of 2019 and approximately 50,000 cubic yards of sediment was removed from the forebay in November 2019 in order to restore ponding capacity.

Post-fire run-off deposited fine sediment in the stream channels which appears to have reduced streambed percolation, resulting in prolonged spring and summer time streamflow, and an increased duration of surface connection between the upper portions of the Ventura River watershed and the Pacific Ocean. Historically, Robles does not experience surface flow during the summer and fall in all but well above-average rainfall years. Surface flow has been present at Robles since the first storm event following the Thomas Fire.

FIGURE 1-2 – Thomas Fire Boundary

Casitas Municipal Water District 3 Hydrology Report Water Years 2018 and 2019

Streamflow monitoring was also impacted by the Thomas Fire. Air lines at the Coyote Creek and Matilija gaging stations sustained fire damage and required repair. The heavy sediment load in subsequent storm events buried the orifices of the air lines at Santa Ana Creek, Coyote Creek, Matilija Creek, and Ventura River Near Meiners Oaks (VRNMO). Further discussion of the impacts and corrective actions taken is included in Section 2.2 herein.

Data from an additional rainfall station located on Ojai’s East End and a San Antonio Creek gaging station were added to this report to reflect hydrologic conditions within the San Antonio Creek Watershed. Ojai Water System Sources and Deliveries were also added to this report. Reporting of the hydrologic aspects of this system may be expanded in the future as more data become available.

Casitas Municipal Water District 4 Hydrology Report Water Years 2018 and 2019

2. WATER YEARS 2018 AND 2019 SUMMARIES The Water Year (WY) is a standard used for reporting hydrological cycles. It begins on October 1 of the preceding year and ends September 30 of the named water year. For this report:

• WY 2018 began on October 1, 2017 and ended September 30, 2018; and • WY 2019 began on October 1, 2018 and ended September 30, 2019

There are four key elements of collected data evaluated this report: 1) rainfall, 2) streamflow conditions, 3) lake storage and system deliveries and 4) ambient air temperatures. Each of these elements are monitored and recorded by CMWD on a daily basis. The following subsections are summaries of the hydrologic characteristics of WY 2018 and 2019.

2.1. Rainfall Rainfall and evaporation data are collected on a daily basis by Casitas at two stations, one at the Casitas Dam and one at the Lake Casitas Recreational Area (LCRA). The methods for data collection are standardized for consistency. Rainfall data for Matilija Dam and Thacher School are obtained from VCWPD. Raw data is provided in Appendix A.

2.1.1. WY 2018 The average of the four rainfall stations was 13.55 inches for WY 2018. This is below the long-term average of 24.02 inches. Casitas Dam received 11.49 inches while Matilija Dam received 17.03 inches.

The bulk of precipitation at Casitas Dam fell in the months of January and March, when cumulative monthly rainfall was 2.83 and 8.43 inches, respectively. The highest daily rainfall was recorded on January 9, 2018 with 2.10 inches of rainfall measured at Lake Casitas Recreation Area (LCRA).

2.1.2. WY 2019 The average of the four rainfall stations was 31.49 inches for WY 2019. This is above the long-term average of 24.15 inches. Casitas Dam received 29.49 inches while Matilija Dam received 39.75 inches.

The bulk of precipitation at Casitas Dam occurred in the months of January and February 2019, when cumulative monthly rainfall was 9.07 and 9.56 inches, respectively. The highest daily rainfall was recorded on February 2, 2019 with 2.75 inches of rainfall measured at Casitas Dam.

Casitas Municipal Water District Hydrology Report Water Years 2018 and 2019 5 58

2.2. Streamflow Conditions Streamflow conditions are assessed by collecting data at key points in the Ventura River system. Gage station locations are shown in Figure 1-1. Mean daily stream flow data is included in Appendix B.

2.2.1. WY 2018 Due to the drought, streamflow conditions were below average across the basin. Preliminary data provided by VCWPD indicates discharge from North Fork Matilija Creek totaled 3,028.6 acre-feet (AF) between October 1, 2017 and September 30, 2018. Discharge from Matilija Dam measured at the Matilija Hot Springs gage totaled 4,997 AF with a peak flow of approximately 6,200 cubic feet per second (cfs) on January 9, 20181.

Surface flow at the measurement weir at Robles was present beginning January 8, 2018 and lasted the entire WY. During that period, 8,417 AF was released downstream2. Sediment transfer following the Thomas Fire may have impacted percolation and caused elevated surface flow to occur and continue longer than it would have otherwise for WY 2018 and 2019.

Diversions to the Casitas Reservoir began on March 21, 2018. Prior to March 21, all inflow was released downstream to allow for aquifer levels to rise to the extent that would be expected under natural conditions for the time of year and type of year (Trial Operating Criteria for Robles Casitas Diversion Facilities, 1959). The diversion canal was operated for 4 days and 638 AF was diverted during WY 2018 as shown in Table 2-13.

There were three storm peaks that met the Biological Opinion parameters to initiate supplemental downstream releases for fish passage as shown in Table 2-2. Downstream release requirements were met when Robles inflow was sufficient to do so. All flow was released downstream when inflow was less than the required supplemental release4.

Table 2-2 WY 2018 Storm Peaks Date Peak Storm Flow Rate (cfs) January 9, 2018 8,809 March 21, 2018 418 March 22, 2018 3,044

Coyote Creek and Santa Ana Creek drainage areas contribute directly to Lake Casitas storage. Coyote Creek gaging station was damaged during the 2017 Thomas Fire (WY 2018) and subsequently repaired in January 2018. The Santa Ana Creek gaging station was not damaged; both Coyote Creek and Santa Ana Creek gaging stations, however, experienced heavy sediment transport and re-channelization following the fire, rendering poor quality flow data. Direct inflow into Lake Casitas, which is reported in the Casitas Reservoir Operation data (Appendix C), was used as a surrogate for Coyote and Santa Ana creeks as the major tributaries, but also accounts for other direct runoff including smaller tributaries such as Ayers, Chismahoo, Willow, and Poplin Creeks. Direct inflow is a zero sum calculation and accounts for change in Lake Casitas storage not accounted for by precipitation, Ventura River Diversions, evaporation, precipitation, and releases to the Marion Walker Water Treatment Plant. This value may be negative at times which is attributed to approximation in evaporation coefficients and water loss to infiltration. Only months with a positive direct inflow value are considered as a surrogate for true direct inflow into Lake Casitas and totaled 3,475 AF for WY 2018 with March 2018 accounting for 1,723 AF of total direct inflow as shown in Table 2-35.

Table 2-3 WY 2018 Casitas Reservoir Direct Inflow Month Direct Flow Volume (AF) 6 October 2017 13 November 2017 N/A December 2017 N/A January 2018 795 February 2018 87 March 2018 1723 April 2018 225 May 2018 80 June 2018 177 July 2018 161 August 2018 159 September 2018 55 TOTAL 3,475

Casitas Municipal Water District Hydrology Report Water Years 2018 and 2019 7 60

2.2.2. WY 2019 The above average rainfall along with several storm events contributed to significant run-off within the watershed. Preliminary data provided by VCWPD indicate discharge from North Fork Matilija Creek totaled 14,566 AF between October 1, 2018 and September 30, 2019. Discharge from Matilija Dam measured at the Matilija Hot Springs gage totaled 37,812 AF with a peak flow of approximately 1,353 cfs on January 17, 20197.

Surface flow at the measurement weir at Robles was present beginning October 1, 2018 and lasted through September 30, 2019. During that period, 44,712 AF was released downstream to the Ventura River8. A portion of inflow is diverted when inflow exceeds downstream release criteria to: 1) allow for aquifer levels to rise to the extent that would be expected under natural conditions for the time of year and type of year (Trial Operating Criteria for Robles Casitas Diversion Facilities, 1959) and 2) provide supplemental downstream releases to allow for the migration of endangered southern California steelhead (Biological Opinion for the Robles Diversion Fish Passage Facility, Ventura River, CA, 2003). Periods of stream flow were estimated due to post-fire related sediment impacts to stream gaging instrumentation. Flow overtopping the cut-off wall during high flow events bypasses the measurement weir and is estimated during peak flow and is unable to be measured to calculate daily average discharges.

Diversions to the Casitas Reservoir first began on November 29, 2018. The diversion canal was operated for two days in November 2018 and one day in December 2018. Sufficient inflow for sustained diversions began on January 12, 2019. The diversion canal was operated for 140 days and 20,882 AF was diverted during WY 2019 as shown in Table 2-49.

There were nine storm peaks that met the Biological Opinion’s parameters to initiate supplemental downstream releases for fish passage as shown in Table 2-5. Downstream release requirements were met when Robles inflow was sufficient to do so. All flow was released downstream when inflow was less than the required supplemental release10.

Coyote Creek and Santa Ana Creek drainages contribute directly to Lake Casitas storage. These gaging stations continue to be impacted by sediment transport and re-channelization following the 2017 Thomas Fire and are producing poor quality flow data. Direct inflow into Lake Casitas, which is reported in the Casitas Reservoir Operation data, was used as a surrogate for Coyote and Santa Ana Creeks as the major tributaries, but also accounts for other direct runoff including smaller tributaries such as Ayers, Chismahoo, Willow, and Poplin Creeks. Direct inflow is a zero sum calculation and accounts for change in Lake Casitas storage not accounted for by precipitation, Ventura River Diversions, evaporation, precipitation, and releases to the Marion Walker Water Treatment Plant. This value may be negative at times which is attributed to approximation in evaporation coefficients and water loss to infiltration. Only months with a positive direct inflow value are considered as a surrogate for true direct inflow into Lake Casitas and totaled 15,823 AF for WY 2019 with February 2019 accounting for 7,469 AF of total direct inflow as shown in Table 2-612.

10 Storm peak flows can be found in Appendix C. 11 Storm flow is approximate. 12 Direct inflow into Lake Casitas is shown in Appendix D.

2.3. Lake Storage and System Deliveries Water storage volumes for system reservoirs, Casitas Dam and Matilija Dam, were ascertained by the daily recording of the reservoir elevation and applying the elevation number to a storage table for each reservoir. Casitas Reservoir data is included in Appendix C and Matilija Reservoir Data is provided in Appendix E. System delivery data for Mira Monte Well and the Ojai Water System can be found in Appendix F.

2.3.1. WY 2018 Lake Casitas Reservoir had a net decrease in water storage for WY 2018. Lake elevation was 493.38 feet above mean sea level (MSL) on October 1, 2017 and ended on September 30, 2018 at 483.30 feet above MSL, corresponding to 74,894 AF of storage in Lake Casitas at the end of the WY. The reservoir’s 10.1-foot decrease in elevation resulted in a net loss of 12,927 AF. Storage increased by 2,117 AF during the three-month period of January through March; net monthly storage losses occurred outside of that period.

A new Casitas Reservoir storage rating table was adopted after completion of a LIDAR and bathymetric study resulting in a re-calculated reservoir capacity of 237,760 acre-feet (down from 254,000 acre-feet). This table was implemented on October 1, 2017 (start of WY 2018) and Casitas Reservoir storage reported from that date forward will reflect this adjustment.

Water deliveries from the reservoir to the main conveyance system totaled 11,633 AF for the Calendar Year. This is down 5 percent from 2017 and 29 percent from the average deliveries during the previous ten years. Mira Monte well production was 145 AF during WY 2018 and 151 AF during the 2018 Calendar Year. Deliveries within the Ojai Water System totaled 1,830 AF; 1,465 AF of which was sourced from the Ojai System Wellfield with the additional 364 AF coming from Lake Casitas.

13 N/A indicates the month is not applicable because the value was negative.

Casitas exercised water rights to divert water released from Matilija Dam. Water rights were not exercised for several years due to National Marine Fisheries Services (NMFS) concerns related to downstream biological-impacts. The County of Ventura is the owner of Matilija Dam and Casitas operates the valves for releases. At the request of the State of California Department of Water Resources Division of Safety of Dams (DSOD), the valves were operated in November 2017. Casitas did not conduct any controlled releases from Matilija Dam at the dam during the water year. All flow was allowed to spill over the dam for the entire water year.

2.3.2. WY 2019 Lake Casitas had a net increase in water storage for WY 2019. Lake elevation was 483.27 feet above MSL on October 1, 2018 and ended on September 30, 2019 at 502.36 feet above MSL, corresponding to 101,168 AF of storage in Lake Casitas at the end of the WY. The reservoir’s 19.1-foot increase in elevation resulted in a net gain of 26,310 AF. Storage increased by 35,248 AF during the four-month period of January through April; net monthly storage losses occurred outside of that period.

Water deliveries from the reservoir to the main conveyance system totaled 7,668 AF for the Calendar Year. This is down 34 percent from 2018 and 51 percent from the average deliveries during the previous ten years. Mira Monte well production was 138 AF during WY 2019 and 124 AF during the 2019 Calendar Year. Deliveries within the Ojai Water System totaled 1,638 AF; 1,493 AF of which was sourced from the Ojai System Wellfield with the additional 145 AF coming from Lake Casitas.

Casitas exercised water rights to divert water released from Matilija Dam. Water rights were not exercised for several years due to National Marine Fisheries Services (NMFS) concerns related to downstream biological-impacts. The County of Ventura is the owner of Matilija Dam and Casitas operates the valves for releases. A contractor for the County of Ventura unclogged the dam piping and Casitas staff operated the valves on December 7, 2018. Critical Drought Protection Measures (CDPM) were implemented on March 3–4, 2019 in which approximately 101 AF was released from Matilija Dam and diverted to Lake Casitas14. Casitas, in collaboration with NMFS, aimed to minimize potential downstream biological impacts by releasing water from Matilija Dam following a storm peak on March 3, 2019 and during supplemental downstream releases for fish passage.

2.4. Ambient Air Temperatures Data was recorded by CMWD staff at two locations, Casitas Dam and LCRA. These measurements are made on a daily basis and include the maximum and minimum ambient air temperatures and wind speed. This data is included in Appendix G.

2.4.1. WY 2018 Several temperature records dating back to 1960 were tied or broken during the 2018 calendar year: highest monthly maximum (July for Casitas Dam; January and July for LCRA), and highest monthly average (January for Casitas Dam; January and July for LCRA).

14 Results are based on inflow from the Robles canal download.

3.1. Historical Hydrology Period 1959 through 2019 The historical data was updated for the reporting period and is presented in Figure 3-1 for the period from 1959 through 2019. The historical data includes summaries for the Casitas Reservoir operation, Robles Diversion, rainfall, and ambient air temperature. Storage volume, represented by a solid line, is reservoir storage at the start of each calendar year (elevation measured on last day of previous calendar year). Rainfall, represented by data points with drop lines, is the three-station water year average for Casitas Dam, LCRA, and Matilija Dam rain gages. Reservoir volume prior to 1970 (not shown) represents initial filling period after Casitas Dam completion in 195915.

The change in Casitas Reservoir capacity was made due to performance of a bathymetric survey in 2017 which decreased the previously used 254,000 AF to 237,760 AF. This change combined with the 2017-2018 decrease in storage due to drought conditions presented a substantial loss in storage as shown in Figure 3-1.

15 Historical hydrology data is provided in Appendix H.

3.2. Trends The historical section of this summary report contains data tables and figures to illustrate trends experienced by CMWD pertaining to rainfall and water use.

3.2.1. Ten-Year Moving Average of Mean Precipitation The trend presented in Figure 3-2 is a ten-year moving average of precipitation from 1880 to present and was created by calculating an average of a water year’s three-station average rainfall combined with the previous nine years. The ten-year moving average is represented by the solid line traversing across the overall average for the period (24.4 inches). Rainfall data for all three stations are available since 1959, rainfall prior to 1959 was assembled using comparable nearby stations and/or correlation factors with other available stations within the watershed. The trend has resulted in what appears to be a somewhat sinusoidal curve, illustrating reoccurring periods of wet and dry conditions.
